Which one of the followings is an endospermic dicot seed

Options

A. Pea
B. Bean
C. Gram
D. Castor

Answer

To determine which of the following is an endospermic dicot seed, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Definition of Endosperm**:
- Endosperm is a tissue that provides nourishment to the developing embryo in seeds. It can be present in varying amounts and configurations around the embryo.

2. **Differentiate Between Endospermic and Non-Endospermic Seeds**:
- **Endospermic Seeds**: These seeds retain their endosperm at maturity, meaning the endosperm is present and provides nutrition to the embryo.
- **Non-Endospermic Seeds**: These seeds consume their endosperm completely during development, resulting in the absence of endosperm in the mature seed.

3. **Identify Examples of Non-Endospermic Seeds**:
- Common examples of non-endospermic seeds include Gram, Pea, and Groundnut. These seeds do not have endosperm at maturity.

4. **Identify Examples of Endospermic Seeds**:
- Endospermic seeds are typically found in monocots, but some dicots also have endospermic seeds. A notable example of an endospermic dicot seed is the Castor bean.

5. **Analyze the Given Options**:
- If the options provided include Gram, Pea, Groundnut, and Castor, we can categorize them based on the previous knowledge:
- **Gram, Pea, Groundnut**: Non-endospermic seeds (they do not have endosperm).
- **Castor**: Endospermic seed (it retains endosperm).

6. **Conclusion**:
- Based on the analysis, the correct answer to the question "Which one of the following is an endospermic dicot seed?" is **Castor**.

### Final Answer:
The endospermic dicot seed among the given options is **Castor**.
